Purpose To investigate effect of valsartan on expression of Notch pathway and production of extracellular matrix. Methods Urine protein and production of extracellular matrix were measured after diabetic mice were treated with valsartan. The levels of Jag-ged1, Notch1, Notch intracellular domain 1 (NICD1), transforming growth factor-β1 (TGF-β1), TypeⅣcollagen and Laminin were determinated by immunohistochemistry, Western blot and real-time PCR. Results Valsartan suppressed urine protein and production of extracellular matrix in diabetic mice (P<0. 05). Valsartan also inhibits overexpression of Jagged1, Notch1, NICD1, TGF-β1, Type Ⅳ collagen and Laminin in glomerular tissues of diabetic mice (P<0. 05 or P<0. 01). Conclusion Valsartan inhibits activa-tion of Notch pathway in glomerular tissues of diabetic mice, inhibits production of extracellular matrix in glomerulus and delays glomer-ulosclerosis.

Objective Lipid metabolism disorder can lead to male sterility, but its mechanism of affecting spermatogenesis and testis microenvironment remains unclear.This study aimed to investigate the effects of high fat diet on reproductive function and the expression of Ox-LDL within testis in male mice. Methods 16 C57BL/6 mice aged 8 weeks were divided into two groups by random number table method.High fat diet group was fed with high fat diet while normal fat diet group was fed with normal fat diet .At the end of 16 weeks, the levels of TG, TC, Ox-LDL and testosterone in serum were measured.The sperm concentration and motility from caudal epi-didymis were analyzed.The testis structure was observed by HE stai-ning.The localization and expression of Ox-LDL in testis were detec-ted by immunohistochemical technique. Results Compared with the normal diet group mice, the body weight (P<0.05) and the ser-um levels of TC [(2.31 ±0.33)mmol/L vs (6.54 ±0.31)mmol/L, P<0.01], Ox-LDL [(0.32 ±0.03)mg/L vs ( 0.44 ±0.06)mg/L, P<0.01] increased in high fat diet group mice significantly.The serum level of TG was of no significant difference(P>0.05).The serum level of testosterone[(3.64 ±0.43)mg/L vs (0.40 ±0.14) mg/L, P<0.01], the sperm concentration[(9.95 ±0.75)106/mL vs (5.66 ±1.51)106/mL, P<0.01] and the sperm motility[(54.69 ±17.84)%vs (32.48 ±5.80)%, P<0.01] decreased in high fat diet group significantly.HE staining also showed that the amount of Leydig cells, spermatids and spermatozoons reduced obvi-ously in high fat diet group.Immunohistochemistry staining showed that Ox-LDL was mainly distributed around Leydig cells of mice tes-tis.The expression of Ox-LDL in high fat diet group increased significantly ( P<0.01) . Conclusion The expression of Ox-LDL in Leydig cells of high fat diet C57BL/6J mice increases significantly, which may inhibit testosterone biosynthesis and affect spermatogen-ic function.

Objective To explore the characteristics of temporal distribution and epidemic trend of autumn-winter type scrub typhus using the time series analysis.Methods Based on the data of scrub typhus collected from Shandong Diseases Reporting Information System from 2006 to 2011,both spectral analysis and moving average analysis were used to analyze the annual data of scrub typhus while scrub typhus incidence in 2012-2014 was forecasted.Seasonal decomposition analysis was applied to analyze the monthly data from January of 2006 to October of 2011,followed by Autoregressive Integrated Moving Average Model (ARIMA) which was constructed to forecast case number in November and December of 2011 and compared to the actual incidence.Results The results of spectral analysis showed that the prevalence of autumn-winter type scrub typhus had a feature of ‘3-year-periodicity’.A long-term up-trend was confirmed by method of moving average analysis,with annually case numbers of 310,337 and another number of 366 forecasted for 2012 to 2014,respectively,with the annual increase rate as 9％ per-year.Data from analysis of monthly data of scrub typhus showed that through multiple seasonal decomposition analysis,the results indicated that the prevalence of this disease possessed a typical autumn-winter type.The seasonality indexes for scrub typhus in October and November were 8.454 and 2.230,respectively,while others were less than 1.000.The ARIMA (0,1,1 ) (0,1,0)12 model of ( 1 -B) ( 1 -B12)X,=( 1 -0.811B)u,that was used to forecast the prevalence of autumn-winter type scrub typhus and was constructed with the residual error of 16 lags as white noise.The Box-Ljung test statistic for the model was 3.116,giving a P value of 0.999.The model fitted the data well.Good accordance was achieved between the observed values and the forecasted values of scrub typhus in November and December of 2011 which was produced by the ARIMA model,and all observed values were within the forecasted 95％ CI.Conclusion The prevalence of autumn-winter type scrub typhus showed a 3-year-periodicity,with a long-term up-trend,and the case numbers of 2012 to 2014 were forecasted,rising on the end with an increasing rate of 9％ per year,which occurred seasonally with October as the peak time in every year.The ARIMA (0,1,1 ) (0,1,0) 12 model seemed to be quite appropriate in predicting the autumn-winter type scrub typhus.

OBJECTIVETo study clinical effects of unilateral pedicle screw-rod system fixation combined with the single the cage of interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor.

METHODSFrom February 2010 to December 2011, 39 patients with lumbar degenerative instability after invalid conservative treatment were treated with unilateral fixation combined with interbody fusion via the paraspinal intermuscular approach under MAST Quadrant retractor. The indexes such as the operative time, blood loss, complications, VAS pain scores, JOA (subjective symptoms of low back pain,lower limb pain and numbness, sensory disturbance, movement disorders) scores, modified Macnab criteria for curative effect evaluation were observed before treatment, at the 1st month after treatment and the latest follow-up. The intervertebral fusion was studied on the X-ray at the latest follow-up.

RESULTSAll the patients were followed up, and the mean during was (22.3 +/- 8.6) months. The operation time was (138 +/- 46) min, and the amount of bleeding was (335 +/- 152) ml. There were no complications such as cerebrospinal fluid leakage and spinal nerve injury during operation, and no incision infection after operation. The VAS pain score was reduced from preoperative 7.93 +/- 1.27 to 2.05 +/- 1.18 on the 1st month after operation and 1.89 +/- 0.42 at the latest follow-up. The JOA total score was improved from preoperative 1.59 +/- 0.42 to 8.86 +/- 0.37 on the 1st month and 9.02 +/- 0.29 at the latest follow-up. According to modified Macnab criteria, there were 17 cases got an excellent result, 19 good, 3 case fair. Thirty-five patients got intervertebral bony fusion at the latest follow-up.

CONCLUSIONUnilateral pedicle screw-rod system fixation combined with single cage interbody fusion in the treatment of lumbar degenerative instability via paraspinal intermuscular approach under MAST Quadrant retractor is a safe, minimally invasive, satisfactorily effective methods to treat lumbar degenerative instability.
